Victor Timofeevich Zhukov, Наталия Дмитриевна Новикова, О. Б. Феодоритова · Mathematical Models and Computer Simulations · 2014
The proposed algorithm represents an efficient parallel implementation of the Fedorenko multigrid method and is intended for solving three-dimensional elliptic equations. Scalability is provided by the use of the Chebyshev iterations for solution of the coarsest grid equations and for construction of the smoothing procedures. The calculation results are given: they confirm the efficiency of the algorithm and scalability of the parallel code.
